If possible, avoid using the machine with the lever completely pushed forward, since in this way consumptions will be consider- ably reduced and the life of either the engine and the machine will be longer. For a correct use of the lever, keep to the indications given on the plate (1) applied inside the right dashboard. The plate (1) is characterized by two coloured areas, the green area “A” and the red area “B”, referring to different engine rotation speeds: • Green area “A”: this area indicates an engine rotation speed of 1700 rpm, which is the value recommended to the operator. • Red area “B”:

this area indicates an engine rotation speed up to 1900 50 rpm, which is the maximum speed allowed for the use of the backhoe. The engine speed can be checked on the revolution counter positioned on the right dashboard. See “3.3.2 pos. 2 REVOLUTION COUNTER - HOUR COUNTER”. B A RWA33150
